3 Inch Screw Trick That Fixes a Door Not Closing for Brussels Expats
Most doors that won’t latch are fixed by tightening or reinforcing the hinge screws, or by adjusting the strike plate. Before anything else, try this: push up on the door handle while someone tightens the top hinge screw, then watch whether the latch clicks into the frame. If the door still won’t sit flush or the latch still won’t catch after that, work through the checks below. Call a professional if you spot cracks in the wall, several doors sticking at once, or soft, crumbling wood at the frame’s base.

Why is my door sticking or not closing properly?
A door that won’t close is almost always trying to tell you something specific, if you listen to how it fails. Match what you’re seeing to the list below before you touch a screwdriver.
No click when you close it — the latch is missing the strike plate, usually because the door has dropped slightly or the plate has shifted.
Rubs at the top corner — the bottom hinge screws have likely worked loose, letting the door sag forward.
Rubs at the bottom corner — the top hinge is the culprit here, often from a stripped screw hole.
Swings open on its own — the door isn’t sitting square in the frame, or the hinges are worn and no longer holding tension.
Sticks only in summer or after rain — that’s almost certainly wood swelling, not a mechanical fault.
Seasonal humidity is one of the most common and most overlooked causes. Timber doors and frames commonly swell by a few millimetres during damp weather, which is more than enough to stop a latch catching cleanly. That kind of swelling usually reverses once the air dries out, so it’s worth ruling out before you reach for sandpaper.
If more than one door in the house has started sticking at the same time, or you notice hairline cracks running from a window or door frame up into the wall, you’re likely looking at something more structural than a loose hinge. That’s a different repair altogether, and one worth flagging early rather than chasing with screws and shims.
Essential tools and materials to have ready
Half the frustration with door repairs comes from starting a job, then discovering you’re missing one part halfway through. Gather these first.
Manual screwdriver set (flathead and Phillips)
3-inch wood screws for hinge reinforcement
Wooden dowels and wood glue
Cordless drill with a range of bits
Sandpaper (medium grit) or a hand plane
A small flat file for widening the strike hole
Silicone or graphite lubricant
Thin wood or card shims
A spirit level or straightedge
Most of this is available from any general hardware shop or builders’ merchant, and none of it needs to be expensive. If the door is solid timber or a heavy fire door, get a second pair of hands before you lift it off its hinges. Solid doors are far heavier than they look, and a dropped door damages both the frame and your foot.
Step 1: how to inspect a door that won’t close
A quick, methodical check saves you from guessing and repairing the wrong thing.
Close the door slowly and watch exactly where it first makes contact with the frame. Mark that spot lightly in pencil.
Run a straightedge or level down each side of the door to check the gap is even, top to bottom.
Close the door normally and listen for the latch. A clear click means the latch is working; silence or a scrape means the strike plate is out of position.
Check every hinge screw by hand. If a screw spins freely without gripping, that hinge is your priority.
Open and close the door a few times, watching whether it drags along the carpet or the top of the frame.
This short routine is the fastest way to isolate the real cause rather than tightening hinges that were never the problem.
Step 2: tightening and repairing loose hinge screws
Loose hinges cause more “door won’t close” calls than anything else, and they’re also the easiest fix on this list.
Always use a manual screwdriver rather than a power drill for this. Hand tightening lets you feel the screw seat properly, where a drill can easily over-torque and strip the hole further.
If the screw spins without biting, the hole is stripped, not just loose.
Replace short original screws with 3-inch wood screws long enough to reach past the door jamb and into the timber stud behind it. This gives genuine holding power instead of gripping thin jamb wood alone.
For a stripped hole with no stud access, the reliable long-term fix is a dowel repair: coat a wooden dowel in glue, tap it into the enlarged hole, trim it flush once dry, then drill a fresh pilot hole and refit the original screw.
If the door sags and drags along the floor, slide a thin card shim behind the bottom hinge leaf before retightening; shimming the top hinge instead corrects a door that binds at the bottom.
Work one hinge at a time and test the door’s swing after each change, rather than adjusting all three hinges before checking anything.
Pro Tip: Fit that first 3-inch screw through the top hinge into the stud before you touch anything else. It often pulls a sagging jamb back into line on its own, without you needing to remove the frame at all.
Step 3: aligning the strike plate and latch
If your hinges are solid but the door still won’t latch, the strike plate is almost certainly the problem.
Rub a little pencil lead or lipstick onto the latch bolt, close the door gently, then open it and check where the mark lands on the strike plate. That’s your true contact point.
If the mark sits above or below the strike hole, loosen the plate’s screws and shift it a few millimetres in the right direction before retightening.
If the latch is close but not quite catching, use a small flat file or a sharp chisel to widen the strike hole slightly rather than moving the whole plate.
If the door has dropped significantly, or the latch barely reaches the plate at all, a deeper strike box or a full latch replacement is the more durable fix.
A missing “click” on closing is a reliable sign the latch and strike plate have simply drifted out of alignment, not a sign the whole door needs planing.
Step 4: sanding or planing a swollen door edge
This is the last resort, not the first move, and it should only follow the humidity check. If the sticking appeared after a stretch of wet weather, wait a week or two and test again before cutting anything. Wood that’s swollen from moisture usually shrinks back once conditions dry out.
If the sticking persists in dry weather too, then trimming is fair game:
Remove the door from its hinges and lay it flat on a stable surface.
Use your pencil marks from the inspection step to identify exactly where it’s binding.
Sand or plane in small, gradual passes, checking the fit against the frame frequently rather than removing too much in one go.
Always seal the freshly cut edge with paint or varnish afterwards. An unsealed edge absorbs moisture faster than the rest of the door, which just brings the swelling problem back.
For bathroom doors specifically, humidity exposure is constant rather than seasonal, so it’s worth checking door materials suited to damp rooms before assuming a plane is the answer.
Step 5: lubricating hinges and preventing it from happening again
A door that’s mechanically sound but still feels stiff or noisy usually just needs cleaning and lubrication.
Wipe away built-up dirt, dust, and old paint from the hinge pins and the latch mechanism before applying anything.
Apply a light silicone or graphite lubricant directly to the hinge pins and the latch bolt, then open and close the door several times to work it in evenly.
Avoid heavy oils that attract dust and turn gummy over time.
Recheck hinge screws and latch alignment twice a year, ideally at the change of seasons, since that’s when humidity swings hit hardest.
Pro Tip: A dry graphite lubricant is worth keeping in a kitchen drawer. It doesn’t stain paintwork the way oil-based sprays can, and it’s the first thing to reach for on a squeaky hinge.
When should you call a professional instead?
Some door problems are simply beyond a screwdriver and a tube of wood glue, and knowing the difference saves you time and money.
Several doors sticking at once, or visible cracks running from door and window frames, point to structural movement rather than a simple fix.
Soft, crumbling, or damp timber at the base of the frame usually means rot, which needs the damaged section cut out and replaced rather than patched.
Doors that need re-hanging, new frames, or carpentry adjustments are faster and cheaper to get right the first time with a tradesperson than after several DIY attempts.
Before booking a visit, take clear photos of the gap, the hinges, and any cracking, and note roughly how long the door has been misbehaving. That lets a professional quote accurately and arrive with the right materials the first time.
How Eutradesmen fixes doors for English-speaking residents
Eutradesmen’s handyman team handles exactly this kind of job daily, from a single sticking door to full carpentry repairs, and always in clear English from first message to final invoice. One recent case saw a same-day door repair completed for an expat household in Brussels, where a sagging bedroom door that had been jammed shut for weeks was rehung and latching properly within the hour.
On a typical visit, the technician checks hinge alignment, strike plate position, frame squareness, and looks for any signs of rot or humidity damage before deciding on the fix. Most sticking or non-latching doors are resolved on the spot, without a second visit.
To get a quote, simply describe the problem, share a photo if you can, and mention which room and how long it’s been happening. That’s usually enough for an accurate estimate before anyone even arrives.
Our honest take on DIY door repairs
Most online advice treats every sticking door as a carpentry job, sending readers straight to a plane and sandpaper before they’ve even checked a hinge screw. That’s backwards. The research behind this guide, and the pattern we see in call-outs across Brussels, Waterloo, Tervuren, and Leuven, points the same way: the overwhelming majority of “door won’t close” complaints come down to a loose screw or a misaligned strike plate, not a swollen door needing surgery.
The fix priority should always run from least invasive to most invasive. Tighten and reinforce hinges first. Check the strike plate second. Only reach for sandpaper or a plane once you’ve ruled out humidity as a temporary cause. Skipping straight to trimming the door edge is the single most common DIY mistake we see, and it’s often irreversible once you’ve cut too much.
Renters especially should think twice before altering a door permanently. A hinge shim or an extra screw is easy to explain to a landlord. A planed-down door edge is not.

FAQ
How do you fix a door that won’t close?
Start by tightening the hinge screws with a manual screwdriver, then check whether the latch clicks into the strike plate. If the hinges are solid but the latch still won’t catch, the strike plate likely needs repositioning or the hole needs widening slightly with a file.
Why does my door keep opening on its own after I close it?
This usually means the door isn’t sitting square in its frame, often because a hinge has worked loose or the door has dropped slightly. Tightening the top hinge, or adding a thin shim behind it, typically stops the drift.
Why isn’t my door closing when I press the latch?
A latch that won’t catch when pressed is almost always a sign the strike plate has shifted out of alignment with the latch bolt. A quick pencil or lipstick mark test on the latch bolt shows exactly where the plate needs to move.
Why do I have to push my door hard to close it?
Needing extra force usually points to either a swollen door edge from humidity or a hinge that’s let the door sag into the frame. Check for seasonal swelling first, since that often resolves on its own once the weather dries out, before assuming the door needs trimming.
